The invention is based on an HVAC (heating, ventilation and air-conditioning) system which comprises the following components: a) a fluid flow duct (1), b) a fluid flow valve (7) which is arranged therein and has a valve body (5) in the fluid flow duct (1) and a valve motor (15) which moves the valve body (5), c) a control circuit for activating the valve motor, d) a sensor (8) in the fluid flow duct (1) and e) an evaluation module for evaluating signals of the sensor. In order to produce an automated functional control, the following procedure is adopted: f) a first actuation signal is preset for the valve motor by the control circuit, and the actuation signal corresponds to a first setpoint position of the valve body (5), g) registration of a first signal of the sensor (8) by the evaluation module, and h) determination of a functional diagnosis of the fluid flow valve on the basis of the first signal of the sensor. |
